Heat & Screed Ltd now offer a screed BRE test service (also known as a drop hammer test) using our own
BRE test equipment. This is a test for soundness of floor screed which can be affected by a number of
variables including; poor compaction, moisture content, insufficient binder (cement).
The BRE test is carried out using a device which consists of a 1m long, cylindrical guide rod, along which an
annular weight of 4 kg (or 2kg for floating screeds) travels when released. At the bottom of the guide rod the
weight strikes the collar of a case-hardened steel anvil which transmits the impact to the selected area of the
Four successive impact blows on the same spot are sufficient to test the soundness of the screed.
The depths of the indentations are then measured with an electronic depth gauge. Any area where the impacts
produce an indentation of 3 mm or less can be considered sound, according to current data. Where the
indentations are greater than 5 mm the screed may fail when in use.
We can offer solutions for failed floor screeds including: the removal and re-laying with fast setting &
drying products or the use of specialist penetrating resins.
